An exterior of the cathedral church, showing the south transept in the foreground, with the...

The image shows the eastern aisle of the south transept, which was likely built between c1230-40, and a partial view of the clerestory arcade on the exterior with arched windows. In the foreground is an octagonal turret on the eastern corner of the south front, with a tapered roof on top. This turret is mirrored by a second turret that stands against the central gabled bay. On the right of the transept is a low extension that was formerly used as a treasury, now known as the consistory court. Behind this low building is the choir south aisle, which has two roof levels and large traceried windows. Above the aisle is a pierced parapet with quatrefoil design and crocketed pinnacle, and above the choir is an openwork battlement parapet with the crocketed pinnacls repeated. In the background is the square crossing tower with two large three-light windows on all fronts and an openwork embattled parapet.
